Basically, jbpm version control follows the following principles:
1) each time a process is released, a new process definition will be generated in the database.
2) a version number will be assigned to the process definition at the time of release. If the process name is the same, jbpm considers it to be the same process definition.
Add 1 to the current maximum version defined by the same process. If not, the new version number is 1. You can obtain
The latest version of a process named.
3) Once a process instance is started according to a process definition, it will not change the process definition and will continue to run until the instance is completed. In this way, the process
The instance is started according to the latest process definition and runs according to the process definition throughout its lifecycle.
4) A process definition has its own business programming logic. jbpm can differentiate the business logic corresponding to different process definitions.
